These when placed on container portion! formed by scored or creased lines land 40 v necks are formed into a series of sections sepapreferably of polygonal form, said portion being rated by plaits all extending in one directlon'and folded down along said lines when applied to a the lower part of the blank is folded inwardly'and container mouth. Joined to the edges 4 of the I upwardly to retain the cover in place on the concontainer mouth covering portion are the flaps tainer neck. This construction involves an opor'sections 5 which are all substantially of equal eration of folding which is very difficult and ex'- height. As shown in Fig. 1 the sections 5 are of pensive to effect satisfactorily on any practical difl'erent sorts alternating with one another and capping machine. Furthermore this form of separated by triangular portions 8, which when cover is diflicult to remove from the container top the cover is on the container are developed into so when it is desired to use the contents of the confolds such as I and 8. 5 tainer, My improved container cover avoids the Preferably the sections 5 all end in tabs but the f in dimculties and is readily applied by latter may be-of different shapes. They are all .machine and has improved means'for removing substantially of the same height as indicated in it from the container. I Fig. 2. In the form of blank shown in Fig... 1 the 56 Embodimentvofthe means I prefer toemploy numbers it and II refer to the two different sorts of sections shown in this form, and said sections respectively end'in the tabs l2 and II. The tabs I 2 are pre-cemented or coated with cement or adhesive l4 and the tabs ii are also pro-coated with the same.

In applying'a cover to a container, a blank 2 is placed on the container mouth m of the container C and the sections 5 are pushed down around the container neck, the wider sections l0 being pushed down first. The tabs l2 arenext pushed into place and may be pre-folded along the scored lines l6. and when this is the case their side parts II extend over the line 8a which define one of the folds 3 at its upper part and defines the slot I! at its lower part.

The tabs l3v are next pushed in behind the other skirt parts as shown in Fig. 2 and pressure is brought to bear all around the container neck 0 and where the cement is adapted to be softened by heat, the same is also applied to the skirt portion, preferably by suitable folder members such as those containing electric heating coils.

It will be noted that the parts I] of the tabs 1 l2 constitute interlocking pre-coated tabs with the tabs I 3 which are positioned behind them. The interlocking tabs on being heated and cooled preferably under pressure, form so firm a union.

that tampering with the cover is practically impracticable. Furthermore such tampering would render the package unsalable.

The form of the invention shown in Figs. 6 and '1 is similar to the foregoing but diflers therefrom partly in having less depth in the slots 18 and also in being of an octagonal form at the central or mouth covering part, so that the various parts assume a somewhat different relation 1 to each other than those in Figs. 1 to 5 inclusive. The form shown in Figs. 8 and 9 differs from the foregoing forms by the elimination of the slots l3 and in extension of the triangular parts 3, and differs from the form in Figs. 6 a 7 py having the central portionhexagonal.

In the form of the device shown in Fig. 10, the blank 20 is of a circular form and has a scored polygonal central portion 22 surrounded by the flaps or sections 33 and 29 of substantially equal height scored therein, triangular scored portions 23, and tabs 26 and 2! of substantially equal height but of greatly different widths and separated by the slots 28.

Fig. 11 shows the application of this blank to a container neck and wherein the tabs 21 are first folded between the skirt portion 2| and the container neck, and the tabs 26 are then folded between the skirt portion 2| and the container neck andthe extensions 29 of the tabs 21 extend under the fiap 23. The folds or plaits 30' point toward each other. Cement 3! is indicated on the tabs 26 and 21 and may be of the variety which softens by heating it or only one set of the tabs may be coated with that variety and the other set may have another sort of cement or adhesive so that it will be more difilcult to undue the parts from one another.

Fig. 12 shows a blank '32 in which flaps or sections 33 and 34 surround the central or container mouth covering portion 33 and are separated by triangular portions 33 and slots 31, all

of which parts ei'rcept the slots are formed by scorings. "The naps 33 are provided with tabs 38 and 39, and the flaps 34 have tabs 49 which may sometimes be pre-folded on the lines 4|.

' The tabs 38 are folded behind the flaps 33 and there are scorings H or sometimes lines of perforations a, so that the strip can be torn out of the flap 33 on pulling the tab 39 upwardly. There being several of tabs 39, a failure of one will not'prevent the container from being opened by use of the tearing tab as it is very unlikely that all of them would fail.

In the forrnshown in. Fig. 14, 33a and 34a-are the flaps or sections, 35a is the container mouth covering portion, 36a are the triangular portions and 31a are the slots separating the sections. 38a and 39a are the tabs on. sections 34a, and 46 denotes the tabson sections 33a. 44a indicates the rows of perforations defining the strips 45a. From the drawings it will be clear that this form is similar to that of Fig. 12 except that the tearing tabs 39a are on the wider flaps 34a.

What I claim is:

1. A container cover comprising a container mouth covering portion, a skirt portion depending therefrom and including a plurality of sections of equal height at their central parts, ending in tabs of equal height, the tabs defined at their sides by slots in the blank-and folded inwardly between the container neckand the adjacent skirt parts, the adjacent side portions of the tabs interlapped with each other, and means on the adjacent surfaces of said side portion. I

2. A container cover comprising a container mouth covering portion, a skirt portion dependtions for holding the tabs in the interlapped posling therefrom and including a plurality of secmouth covering portion, a skirt portion depending therefrom and including a plurality of sections of equal height at the central part, each ending in a tab, said sections separated by depending lapped elements, said tabs folded between the container neck and the adjacent skirt parts secured thereto by non-metallic means, and a downwardly disposed tearing strip in one of said sections free of the folded and lapped parts,
